Application October 21, 1957, Serial No. 691,304

3 Claims. (Cl. 189-34) This invention relates to structural members,and, moreparticularly, to a metal nailing beam or rstud lnto which nailsmay be driven.

A primary object of the invention is to provide such a nailing beamwhich may be employed as a substitute for a conventional wooden stud inbuilding construction and to which interior finish Wall panels may benailed.

A further object of the invention is to provide such a nailing beamwhich, despite a wide variation in manufacturing tolerances andsubstantial variations in nail dimensions, will grip and hold nailsdriven thereinto.

Still another object of the invention is to provide such a nailing beamwhich does not require special types of expensive nails, but which willgrip and hold the cheapest types of conventional nails.

Another object of the invention is to furnish such a nailing beam havinga simple construction'which is cheap to fabricate.

Other objects and advantages will appear from the followingspecilication and drawings, which are for the purpose of illustrationonly, and in which:

Fig. 1 is a perspective view, partly in section, of a longitudinalsegment of the invention; and

Fig. 2 is a cross section on the line 2-2 of Fig. 1 and illustrates wallpanels nailed to each side of the nailing beam.

Referring to the drawing, I show a nailing beam comprising a pair oflongitudinal mating members 11 and 12, each of which has a ilat centralweb portion 13 provided with two pairs of longitudinal undulations 14and 15 adjacent its outer edges. The member 11 has a pair oflongitudinal ilanges 16 and 17 along its outer edges, and the member 12has a similar pair of llanges 18 and 19 along its edges. The anges 16,17, 18, and 19 are identical and each ilange, referring to the flange 18for example, includes an outer flange portion 20 which is bent outwardlyat an angle of about 45 degrees from the central web 13, and has alongitudinal undulation 20a therein, includes a flat outer face portion21 bent inwardly from the outer edge of the outer ilange portion andperpendicular to the Web portion 13, and includes an inner flangeportion 22 bent inwardly at an angle to the outer face portion andsubstantially parallel to the outer ilange portion 20, the Width of theange portion 22 being such that its inner edge engages in spring contactthe inner edge of the flange portion 22 of the flange 16.

The longitudinal members 11 and 12 mate together as shown, with theinner surfaces of their webs 13 in faceto-face contact and theirlongitudinal undulations 14 and 15 likewise mating, and are rigidlysecured together as by metal stitching 23. The mating of thelongitudinal undulations 14 and 15 of the members 11 and 12 serves toindex the members together in their desired relative positions duringmanufacture, and they and the longitudinal undulations 20a -serve tostrengthen the entire structure, both of which are objects of theinvention.

2,913,076 Patented Nov. v17, 1959 ICC When so assembled, the adjacentinner edges 24 of they inner flange portions 22 engage each other inspringy contact.

As shown in. Fig. 2, the nailing beam 10 may be used to-space a pair ofwooden panels 25 and 26 or the like,A`

conventional nails 27 and 27a being. driven through the panels andbetweenk the inner edges 24 of the longitudinal anges 16, 18 and 17, 19.In doing so, such inner edges, spring apart to admit the nails and tore,-

exercisedl by the'workman other than to drive the nails into therelatively wide nail receiving throat between the outer ilat faceportions 21 of the longitudinal ilanges (16 and 17). Such ilat outerportions 21 provide a ilat bearing surface of substantial areaengageable with the panels 25 and 26, which is another feature of theinvention.

Formed in the central web portions 13 of the longi-V tudinal members 11and 12, at spaced intervals as desired, are registering openings 28 and29, respectively. Such openings are provided to permit electric wiring,conduit, or the like, to be passed through the nailing beam.

My nailing beam 10 provides a simple, rigid construction which is easyand economical to fabricate and assemble, and is readily employed inplace of conventional wooden beams or studs.

Although I have shown and described a preferred embodiment of myinvention, I do not desire to be limited thereto, but desire to beailorded the full scope of the following claims.

I claim as my invention:

1. A nailing beam including: a pair of longitudinal mating members, eachof said members having a generally ilat central web and having alongitudinal ilange on each side thereof, each of said webs having aplurality of longitudinal undulations adjacent the llanges, theundulations of one of said webs mating with the undulations of the otherof said webs, said webs being in back-to-back contact throughout theirlength and Width, each of said ilanges comprising an outer llangeportion bent outwardly at an angle of about 45 degrees to its web andhaving a llat outer face portion bent inwardly from the outer edge ofsaid outer ilange portion and perpendicular to said web, and having aninner ilange portion bent inwardly from the inner edge of said outerface portion and parallel to but spaced from said outer ilange portion,said inner flange portions forming a nail-receiving throat for guiding anail between said Webs at the undulations and having an entry spaceseveral times as large as the nail to be received thereby, the width ofeach inner ilange portion being such that its inner edge engages inspring contact the inner edge of the adjacent inner ilange portion ofthe other member.

2. A nailing beam inclu-ding: a pair of longitudinal mating membersfastened together in back-to back relationship, each of said membershaving a generally ilat central web and having a longitudinal ilange oneach side thereof, each of said flanges comprising an outer llangeportion bent outwardly at an angle of about 45 degrees to its web andhaving a at outer face portion bent inwardly from the outer edge of saidouter ilange portion and perpendicular to said web, and having an innerilange portion bent inwardly from the inner edge of said outer faceportion and parallel to but spaced from said outer llange portion, saidinner flange portions forming a -nail-receiving throat having an entryspace several times as large as the nail to be received thereby, thewidth of each inner ange portion being such that its inner edge engagesin spring contact the inner edge of the adjacentA tions of one of saidwebs mating with the undulations` of the other of said Webs, said websbeing in back-toback contact' throughout their length and width, saidwebs being rigidly secured together adjacent said undulations atspaced-apart points so that a nail may be driven between said matingundulations to force them.

apart to gnp and hold the nail, each of said flanges comprising an outerange portion bent outwardly at an angle of about 45 degrees to its webwith a longitudinal undulation therein and having a at outer faceportion bent inwardly from the-outer edge of said outer flange portionand perpendicular to said web, and having an inner ange portion bentinwardly from the inner edge of said outer face portion and parallel tobut spaced from said outer flange portion, said inner flange portionsforming a nail-receiving throat for guiding a nail into said matingundulations and having an entry space several times as large as the nailto be received thereby, the width of each inner flange portion beingsuch that the distance between its inner edge and the inner edge of theadjacent inner flange portion of the other web is less than thethickness of a nail to be driven therebetween.
